Cone/Spacer Stacking

Cone/Spacer Stacking

60 Degree Cones & Spacers stacking principles.

Illustration (A) above is a basic symmetrical stack up using (7) 60 Deg cones and (7) .750" long spacers with (1) 1.200" long muzzle end spacer for a 7.750" length DM tube, but the same principle apply to any other tube manufacture.

You must know what inside diameter and length tube you have, or are planning to purchase, before you can choose the internal cones and spacers listed on this website. The cones and spacer diameters are listed by the Inside Diameter(I.D.) of your tube. You can stack the cones and spacers however you feel would work best for your application and with some simple math you can choose the right cone/spacer stack for your build.

The stack length of (1) cone and (1) standard .750" long spacer is 13/16"(.812").

Remember that your stack length must fit within the tube length you have chosen minus (subtracting) both cap thread lengths.

Please understand that we can not control the tolerance of other manufactures tube lengths, so we also add .01" plus tolerance in the muzzle end spacer length to try to encapsulate the stack within the tube, rather than bottoming the caps out on the end of the tube, which would result in rattle of the stack in the tube when tightly assembled.

Illustration (A) above shows an example of a 7.750" long Diversified Machine tube, with a standard symmetrical cone/spacer stack up. We are selling the cones and spacers by the piece so for example:

If you want to purchase the standard symmetrical stack up for the 7.750" length tube shown in illustration A you would buy (7) cones that fit the inside diameter of your tube, (7) .750" spacers that fit the inside diameter of your tube & (1) 1.200" long muzzle end spacer that fits the inside diameter of your tube.

Below is a list of standard cone/spacer stack up suggestions for DM Premium Titanium tubes.

The above stacks are for standard symmetrical stack up, with .750" spacers. You can substitute the .750" spacers with different length spacers or mix spacer lengths to come up with your own stack configuration.
